UPDATED ACTUAL Questions and
CORRECT Answers
SAD stage 1 - CORRECT ANSWER - This lauge hansen classification type fracture is
TRANSVERSE/HORIZONTAL fx of the distal fibula/lateral malleolus BELOW the ankle joint.
Tib-fib syndesmosis lig is always intact for all SAD fxs.
SAD stage 2 - CORRECT ANSWER - This lauge hansen classification type fracture is a
classic VERTICAL fracture of the MEDIAL MALLEOLUS BELOW the ankle joint. Tib-fib
syndesmosis lig is always intact for all SAD fxs.
PAB stage 1 - CORRECT ANSWER - This lauge hansen classification type fracture
involves rupture of the deltoid lig or transverse avulsion fracture of the medial malleolus AT the
level of the ankle joint.
PAB stage 2 - CORRECT ANSWER - This lauge hansen classification type fracture
involves rupture of the AiTFL and PiTFL or avulsion of small fragments of bone from tibia or
fibula AT the level of the ankle joint.
PAB stage 3 - CORRECT ANSWER - This lauge hansen classification type fracture
involves classic short oblique fracture of the lateral malleolus on AP view but appears transverse
on lateral view.
SER 1 - CORRECT ANSWER - This lauge hansen classification type fracture involves
disruption of the AiTFL or avulsion fractures of fibula (wagstaffe) AT the level of ankle joint.
SER 2 - CORRECT ANSWER - This lauge hansen classification type fracture involves a
classic spiral fx of the lateral malleolus running anterior inferior to superior posterior AT the
level of the ankle joint. On both AP and lateral view, fx appears oblique.
, SER 3 - CORRECT ANSWER - This lauge hansen classification type fracture involves
disruption of the PiTFL or volkman fragment (fx frag from post mall) AT the level of the ankle
joint.
SER 4 - CORRECT ANSWER - This lauge hansen classification type fracture involves
rupture of deltoid ligaments or transverse fx of medial malleolus.
PER 1 - CORRECT ANSWER - This lauge hansen classification type fracture involves
disruption of the deltoid lig or transverse avulsion fx of medial malleolus ABOVE the level of
the ankle joint.
PER 2 - CORRECT ANSWER - This lauge hansen classification type fracture involves
rupture of AiTFL ABOVE the level of the ankle joint.
PER 3 - CORRECT ANSWER - This lauge hansen classification type fracture involves
sydesmotic rupture and high fibular fx ABOVE the level of the ankle joint.
PER 4 - CORRECT ANSWER - This lauge hansen classification type fracture involves
disruption of PiTFL or avulsion of volkman frag ABOVE the level of the ankle joint.
Rower - CORRECT ANSWER - Classification system for all extra-articular calcaneus
fractures
type 1 A - CORRECT ANSWER - Rowe class involving fracture of the calcaneal
tuberosity. Treatment usually includes BK cast for 6 weeks then WB if non-displaced but ORIF
if displaced.
type 1 B - CORRECT ANSWER - Rowe class involving fracture of the sustentaculum tali.
type 1 C - CORRECT ANSWER - Rowe class involving fracture of the anterior process of
calc. It is the most common subtype of type 1 and only calc fx where females have higher
incidence. Occurs usually from plantarflexion on a supinated foot.
